Abstract:
Objective To introduce the clinical apply of middle and small skin defect in finger injury with lateral arm free perforator flap.Methods (1) Ten cadavers were injected with a modified lead oxide-gelatin mixture.Later,CT scan,three-dimensional reconstruction of the cutaneous perforator vessels on the later arm.Then simulate the flap design.All cadavers were dissected before CT scanning.(2) Eighteen cases of middle and small skin defects in finger injury were treated with lateral arm free flap.The defect area were from 3 cm × 4 cm to 6 cm × 9 cm.Results Our research showed that the average caliber diameter of perforators of profunda brachial artery(PBA) was (0.71 ± 0.15) mm,and Posterior radial collateral artery(PRCA) was (0.94±0.22)mm.The results of pedicle length of perforator of PBA was (2.74 ±0.42) cm:(2.96 ±0.37) cm,and PRCA was (4.78 ±0.63) cm:(4.86 ±0.51) cm.3D reconstructive results showed that the perforators of PBA and PRCA dominated the lateral upper arm area.The flap of 18 cases survived after the operation.The wound of providing area was directly sutured or skin grafting and got healing.All cases were followed up for 6 months to 3 years,and the average follow-up time was 11 months.There was a little swelling on the outlooks of the flap,but the texture and sensation of the flap was good.Conclusion The lateral arm free perforator flap has a stable vessel pedicle,good texture and sensation,so it was a good method to repair middle and small skin defect in finger injury.
